摘要
目的 评价临床致病性酵母对抗真菌药物敏感性及耐药性。 方法 根据美国国家临床实验室标准化委员会 M27- A微量稀释法对临床致病性酵母作了氟康唑、二性霉素 B、 5-氟胞嘧啶、伊曲康唑及酮康唑 5种抗真菌药物敏感性测定。结果 65株念珠菌属的 MIC范围为: 氟康唑 0.125~ 64μ g/ mL, 95.38% (62/ 65)敏感 ,2株耐药,占 3.08%;伊曲康唑 0.03~ 2μ g/ mL, 63.08%( 41/ 65)敏感, 3株耐药,占 4.62%; 5-氟胞嘧啶 0.125~ 32μ g/ mL, 93.84%( 61/ 65)敏感, 2株耐药,占 3.08% ;二性霉素 B 0.06~ 2μ g/ mL,96.92% (63/65)敏感, 2株耐药,占 3.08% ;酮康唑 0.03~ 0.5μ g/ mL,全部敏感( 65/65)。 35株新生隐球菌临床分离株对 5种抗真菌药物的 MIC范围分别为:氟康唑 2~ 64μ g/ mL,伊曲康唑 0.25~ 1μ g/ mL, 5-氟胞嘧啶 0.25~ 64μ g/ mL,二性霉素 B 0.03~ 1μ g/ mL,酮康唑 0.125~ 1μ g/ mL。结论 美国国家临床实验室标准化委员会 M27- A微量稀释法具有操作简便,实用性强,结果稳定,重复性好的优点。临床致病性酵母及其不同的菌株对 5种常用抗真菌药物的敏感性存在差异。
Objective To evaluate the sensitivity and resistance of pathogenic yeasts isolated from patients to antifungal agents. Methods The in vitro susceptibilities of pathogenic yeasts isolated from clinical patients to amphotericin B(AmB),5- flucytosine(5- FC),itraconazole(ICZ),ketoconazole(KCZ) and fluconazole(FCZ) were determined by NCCLS M27- A method. Results MIC ranges of 65 strains of Candida spp.were: FCZ 0.125~ 64μ g/ mL, 95.38% (62/ 65) were sensitive,2 strains(3.08% ) were resistant; ICZ 0.03~ 2μ g/ mL, 63.08%( 41/ 65) sensitive,3 strains(4.62% ) were resistant; 5FC 0.125~ 32μ g/ mL, 93.84%( 61/ 65) sensitive, 2 strains(3.08% ) resistant; AmB 0.06~ 2μ g/ ml,96.92% (63/65) were sensitive,2 strains(3.08% ) were resistant; KCZ 0.03~ 0.5μ g/ mL,all strains(65/65) were sensitive. For 35 strains of Cryptococcus neoformans, the MIC were: FCZ 2~ 64μ g/ mL, ICZ 0.25~ 1μ g/ mL, 5FC 0.25~ 64μ g/ mL, AmB 0.03~ 1μ g/ ml ,KCZ 0.125~ 1μ g/ mL. Conclusions NCCLS M27- A micro dilution method is reliable, practical, reproducible and easy to use in the clinical laboratory. The sensitivity of various species and strains of fungi to the above mentioned antifungal agents is different.
